Office Script code to print to PDF

Hi, I'm getting crazy trying to find a solution. I'm working on a share excel on micro 365 for team work, and on this excel we sant to print by clicking a button, just to print to pdf and save in the computer.

As I know this version doesn't work with VB, just basic java script and I cant manage it to find the code to just print a selection of cells.

Thank you very much and aprreciate for any help.
